DRAG-BAR FOR CULTlVATOR-BEAMS.

SPECIFICATION forming part of Letters Patent No. 297,914, dated April 29, 1884. Application filed November 26, 1883: (No model.)

To all whom it may concern.-

Be it known that I, BYRON O. BRADLEY, residing at Chicago, in the county of Cook and State of Illinois, and a citizen of the United States, have invented a new and useful Improvement in Drag-Bars for Cultivator-Beams, of which the following is a full description, reference being had to the accompanying drawings, in which Figure 1 is a side elevation showing the drag-bar raised and the beam down for use; Fig. 2, a top or plan view of the beam with the handle, shovel-standards, and shov'els removed; Fig. 3, an under side view of the plowbeam without the handle, shovel-standards, and shovels; Fig. 4, a side elevation showing the drag-bar down and the beam elevated out of use; Fig. 5, a detail showing the springcatch and drag-bar end.

The object of this invention is to apply a drag-bar to beams of that'class of cultivators termed tongueless, and have such drag-bar firmly locked in both its elevated and depressed positions, thereby preventing accidental displacement of such drag-bar in use, no matter whether it is elevated or depressed; and its nature consists in pivoting the dragbar in a mortise or recess formed in the forward end of the beam, and having its upper end, when the drag-bar is depressed, project above the top of the beam and engage with the hole or opening in aspring-plate attached to the upper face of the beam, and thereby lock and hold firmly the drag-bar in its depressed position, and having this end, when the drag-bar is raised, engage with the springplate and lock and hold the drag-bar in its eleother suitable material.

vated position, all as hereinafter more specifically described, and pointed out in the claim.

In the drawings, A. represents a beam made of wood or other suitable material, and having at its forward end a mortise,-A. The beam is to be provided with a handle,and with one or more standards carrying the shovels, as usual.

B is the drag-bar, made of wrought-iron or This bar is attached to the beam by passing its end through the mortise A, and securing it by a suitable pin or pivot, a, and the end I) of this drag-bar is longer than the depth of beam from the pivot a to the top, so that when the drag-bar is down this end b will project above the top of the beam, and the ground end I) of the drag-bar is widened and curved, so as to run easily and have a bearing on the ground.

- O is aspring or spring-plate, one end of which is attached to the beam by a suitable bolt, or otherwise, so as to have its free end over the mortise A. The spring or springplate has an upward bend or curve, c, which raises its free end above the top of the beam, and in the free end is formed a hole or opening, 0, into which the endb of the drag-bar enters when the drag-bar is depressed, forming an engagement between the end b and the spring or spring-plate, by which the drag-bar will be locked and held firmly against the travel of the machine when in position for holding the beam elevated, and the bend a is arranged in such relation to the are described by the end b as to allow the end to pass freely, and at the same time, when the drag-bar is raised, as shown in Fig. 1, have the end b engage with the under face of the spring or spring-plate, and lock and firmly hold the drag-bar in its elevated position. The spring or spring-plate G is to be of such rigidity as not to yield readily, and at the same time allow a pull to disengage the end b from the hole 0, or a push todisengage it from the under face of the plate, and the plate 0 and end I) are arranged in relation to each other to have sufficient retention to hold the two together in the ordinary running of the machine.

D is the stirrup, between the arms of which the front end of the beam is pivoted, so as to havea lateral swing.

E is the pipe-box,to which the stirrup D is clasped and secured.

F is the wheel-spindle. G is the arch or axle. 'H is the wheel, between the hubs of which and the arch the pipe-box E is mounted on the spindles F. These parts D E F G H may be of the form of construction and arrangement shown, or of any other'well-known form of construction and arrangement, and they,with the parts of a tongueless cultivator not rep- \Vhat I claim as new, and desire to secure by Letters Patent, is as follows:

The combination, with a beam, A, of the drag-bar B, having a projecting end, I), and a resented, l'orni no part 01' the present inven- 1 tion, which relates simply to the drag-bar and I the pivoting; and locking thereof, so that it will be held firmly in either its elevated or depressed position. The extension or end 6 of spring or spring-plate, 0, having an opening, the drag-bar B,in conjunction with the spring I c, substantially as and for the purposes specior spring-plate O, with which it acts, forms a 5 fied.

look by which the drag-bar is held firmly in position for use, and by which it is also held BY BRADLEY in position when raised and out of use. \Vitnesses:

The drag-bar and spring can be used on other B. A. PRICE, forms of cultivators. O. \V. BOXD.
